' CROVELL Se GO., OF SAME PLACE.

SEEDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 252,528, dated January 17, 1882.

Application tiled October 5, 1881.

To lall whom it may concern:

Be it known that I, HENRY W, SCOTT, of Greencastle, county of Franklin, State ot Pennsylvania, have invented new and useful Iniprovementsin Seeding-lVIachines, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings, making part ot' this specitication, in which-- 1o Figure 1 is a rea-r elevation ot" so much of a grain-drill as is necessary to show my improvement, and Fig. 2 represents a vertical longitudinal section through the same.

My invention relates to a novel arrangement of truss-bar, in connection with a transverse frame or axle-bar, whereby it is made not only to stiften said bar and prevent its sagging under the weight ofthe load, but is also made to assist in relieving` the spring-hoes zo from obstructions by breaking the joint between the hoe and its draw-bnr, and it consists connection with a support or upright intermediate between said supporting-lugs for stit't'ening and supporting said axle-bar midway of' its length, as hereinafter explained.

3o The machine, in its organization or general arrangement and construction, may be similar to such as are now in use, and it need not therefore be described in detail, further than is necessary to explain my improvement.

In the accompanying drawings, A represents the main frame, which may be of the usual rectangular form, A representing the main transverse frame-bar, to which the stubaxles B and B are secured in any usual or 4o preferred manner; or, where desired,a stationary through-axle may be used, constituting both the frame and axle-bar.

C and C are the main carrying and driving wheels mounted on the axles B B.

Upon the inner ends of thestub-axles B B', where the latter are used, are pendent lugs or ears b b', to which the ends of a transverse truss rod or bar, D, are bolted, said bar being (Model.)

therebysuspended horizontally underneath the main frame o r axle-bar, as shown. 5o

To the bar A, midway of its length, is secured a pendent bracket or support, E, which, by preference, is forked or slotted in its lower end to receive the bar D, titting snugly therein. The supportE is made of sufficient length to adapt it, when the bar D has been bolted at one end, and is forced upward into place to be bolted to its supporting-lug, to arch or spring the bar A upward slightly at its center, as shown, and thereby relieve. it from any 6o tendency to sag under the weight of the load ot' grain, Sto., which may be imposed upon it. By reference to Fig. 2 ot' the drawings it will be seen that Athis truss rod or bar D is arranged about in the same transverse line with or slightly in 4advance of the Ljoints between the yielding` or spring hoes F and the drawbars Gr. This arrangement facilitates the breaking of thejoint between the hoe or shoe and the draw-bar when the shoe meets with an 7o obstruction, which would be liable to injure or break it, it' it could not yield to such obstruction, as ordinarily the first effect of such obstruction will be to raise the draw-bar into contact with the truss-rod D, which serves to hold it while the shoe is being crowded backward, overcoming the tension ot' its retainingspring until the shoe is in position to ride over the obstruction. The truss-rod D is thus made to serve the double purpose of stiffening the main 8o frame or axle-bar, and of assisting in the operation of breaking thejoint between the shoe and draw-bar for facilitating the passage of the hoes over obstructions. Another advantage resulting from this arrangement of the S5 truss-rod is that it prevents the drag-bars from rising high enough in passing over an obstruction to allow the hoes tostrike the lugs on the lifting-roller or the tube-board, and thus prevents injury to said parts.

Only one support E is described intermediate between the pendent lugs b b supporting the ltruss-rod D, but it will be apparent that one or more additional supports may be used, where the length of the axle-bar re- 95 quires it.

The hoes or teeth may be hinged to the drawbars in any usual manner, and any usual or preferred form and arrangement of sprin g and retaining devices for holding said hoes in work- 5 ing position may be employed.

Having now described my invention, what I claim as new is- The main frame or axle-bar provided with the suspended truss rod or bar, in combination 1o withthedraw-barsandtheyielding hoes hinged thereto, arranged and operating substantially as described, whereby the truss-rod is made not only to stlen said frame or axle-bar, but also to facilitate the passage. of the hoes over obstructions, as explained. 15

In testimony whereofI have hereunto set my hand this 4th day of October, A. D. 1881.

H. YV. SCOTT.
